, This invention relates to a new and useful improvement. in cold 't-irc setting machines, the object being to construct a machine of the character described the tire or bolts from the .wheel. By my improved machine, the tire can beset cold in from threeto five minutes by having anextended surface'contact along. the edge of the tire by the gripping keys, which do not injure the tire in any way. The machine is operated.

by occentric'shafts, one of which is mounted in theof moving the movable head toward the stationary head. In order that the movement in the design of v machineshownin the drawings may be understood, I will here state that the eccentric shaft in the stationary draw head. is one-half inch off center and consequently by giving the same one-half a revolution an inch movement is imparted to the movable draw head. The eccentric in the movable draw head is threesixteenths of an inch off center and one-half a revolution results in moving the movable draw head threetwo eccentrics is one and three-eighths inches. The eccentric in the fixed draw head is employed vfor finally setting the grip keys and iortaking up movement given by the'ecc'entric in the movable drawhead' This eccentric in the fixed draw headis also used for opening the machine and releasing the tire. On the eccentric mounted in the movable draw head is a large ratchet wheelwhichcodperates with a lever for compounding the leverage in setting heavy tires. In

setting light tires, the lever may be placed in the small hub wrench on the front end of the eccentric in the I movable draw head, which enables the operator to operate the movable draw head from either side.

To adjust the machine to wheels of different diameters, as, from a hind to a front wheel, it is only necessary to remove the bridge plate on which the tire rests and insert one having small radius for a wheel of small diameter. In wheels of smaller diameter adjusting,

wedges are used for' the purpose of supporting the wheel on each side of the bridge plate, the wedges raising the outer ends of the keys until the tops of their teeth" reach the inside edge of the tire.

The machine shown in the accompanying drawings is simple, strong and durable and is capable of setting different sizesof tires on different sizes .of wheels with slight changes in the arrangement of the grippirig'devices and the wheel supports.

My invention consists in the construction, arrange.- ment and combination of the several parts, all as will hereinafter be described and afterwards pointedout in the claims.

In the drawings, 1 indicates a. the support for the moving parts of the machine, which casting has its side walls formed.ascurved guide ways upon which are mounted the fixed and movableheods'. "2 is the fixed head and 3 the movable head. The head, as shown in Fig. 15, is provided with grooves in its lower side edges to take in the inwardly extending flanges of the base casting, the bottom walls of the grooves in the fixed head being provided with inserted wear plates 4 which engage under the flanges on the base casting, see also Fig. 6. The fixed head is later ally movable with respect to the base casting in order Cas ing, forming I that it may accommodate itself in the operation of setting the tire. The movable head is also capable of lateral play to accommodate itself to. a tire and I consider this feature of my invention as important because the wedge keys cannot be made to always act in unison so as to grip the tire uniformly on both sides. By making one or both heads laterally movable, they accommodate themselves to the tire depending upon the action of the grip keys and therefore when power is applied to the movable head, such power will act in the desired direction.

The base casting has a central partition wall 5, see Fig. 7, and the fixed head 2 has a downward extension 6 which is perforated for a bolt 7, said bolt being received by the wall 5. The opening in the extension 6 is of such size as to permit the head .to play laterally without binding'the bolt. Washers 8 are employed between the face of the extension 6 and the .wall 5 to locate the fixed head in its proper position. To further strengthen the fixed head and resist any tilting inclination when in operation, I may use an anchor bar 9 extending under the base casting and connect the same by bolts 10 to the inner lower end of the fixed head. I however do not wish to be limited to the use of this anchor bar as the same may be dispensed with, Where the anchor bar is used, it should be so applied that it will not interfere with'the lateral play of the fixed head in alining itself when the grip-keys are active.

The fixed head, and also the movable head is provided with overlapping extensions 11. illustrated as being in the form of interlocking tongues on their contiguous faces which rest upon the wall 5 and form a support for the bridge plate to be hereinafter described.

The movable head 3 is similar in construction to the fixed head with the exception that it has runners 12 which afford a more extended bearing on the curved run-Way of the base ca ting. Also this movable head is provided with a downwardly extending lug 13, between which and the wall 5 is a spring l4-whose energy is exerted to hold the movable head in its outer position place so that'it can accommodate the lateral movements of the head 2 as well as thelongitudinal move. ment of the head 3 without binding. 1 As this bridge plate forms a support for the tire between the gripping keys, and is under the point: where, the-tire is being upset, it is evident that an important office to be performed by the bridge plate is that of providing a solid I have notshown the different bridge plates in the drawings but in Fig. 19 I have illustrated, by'dotted lines, how a bridge plate with its upper face described from a circle of small diameter would-appear.

17 indicates movable wedges which are employed in connection with wheels of smaller diameter, their use 7 being illustrated in Fig. 7. 1 will say here-thatthe upper faces of the fixed and-movable heads are designed to receive the largest standard size wheels so that whenTthe tires on such wheels are being upset, no extra appliances are necessary. However, when a wheel of smaller diameter is to have its tire upset, a suitable bridge plate is introduced into the machine and when the wheel is arranged in position, the wedges 17 aredriven in underthe keys on each side of the wheel so as to raise the outer ends of the keys. until the upper edges of theirteeth reach theinner edge of the of the wedge keys being similarly inclined for obvious reasons. When the wedge keys are inserted in position, as shown in Fig. 4, it obvious that any outward movement imparted thereto will cause said keys to ride inwardly on the cam seats 19 to grip the tire. 7 These wedge keys are made of different widths in order to take in different tires and in some cases with extremely narrow tires it may be necessary to introduce backing plates 20 behind the wedge keys, see Figs. 4, and 16, which backing plates contribute to the width of the wedge keys. Each wedge key 21 is provided with serrations or teeth 22 preferably'in the form of'ratchet teeth, along its inner lower edge. The tire is designed to be gripped between these teeth and therefore the teeth preferably point inwardly to increase their biting effect.

It is obvious that as an outward movement is necessary to cause the gripping keys to grasp the tire some means must-be provided to accomplish this motion. If the gripping keys were driven outwardly as by the blows from a hammer, their motion would not be uniform, and the tire would not be centered which would result in drawing upon the lateral motion of the heads at the setting of each tire. I prefer to provide 'means for moving the gripping keys outwardly to initially set them in position against the tire so that i when the-gripping keysare finally set, the motion necessary to,effect such final setting would be comparativelyslight, but at the same time, as uniform as possible. I

Referring now to Figs l, 2 and3, it will be observed that each head is provided with a bracket 23 at its outer end, upon which is mounted an operating handle 24.

This handle has connected to it a spring 25 whose other end is connected to a rocking member 26. This rocking member is connected toa'rock shaft 27, see Fig. 3,

whichrock shaft carries at its opposite end a' rocking member 28. Both the members 26 and 28 are'slotted, as at 29, and in these slots are arranged pins 30 extend. ing from the gripping key actuating devices illustrated the gripping keys- When the tire is .in position between the gripping keys, the handle 24 is grasped, and turned down, the tension of spring 25 rocks the members .10 26 and 28,:and the sliding plates 31 are moved outwardly in unisonptheir'projections 36 picking the gripping keys. and-movingthem together, away from the center of the machine which results, due -to the inclination of the inclined seats 19 in the gripping keys approaching each other so asto grasp the tire.

The gripping keys should be of such width that. the motion of the handle 24 will not be exhausted before the teeth of the grippingkeys take hold, because the handle 24 moves past the dead center and is locked in such position, the spring being heldconstantly under tension when the handle is'depressed soas to be in readiness to take up any lost motion in the gripping keys in the event that inequalities in manufacture, dirt or otherthings interfere with their taking hold of the tire in the proper way at the proper time. Itwill thus be seen that the gripping keys are in yielding engagement with the tire but such yielding engagement will not effect the positive gripping action of the teeth to such an appreciable extent as to affect the successful operation of the machine. The gripping keys on the fixedand'movable heads are provided with corresponding mechanism for initially setting'the gripping keys.

The fixed head furnishes a bearing for an eccentric shaft 38 see Fig. 5, and the movable head has also an eccentric shaft 39 mounted therein. ,These eccentric shafts bearings in links 40, the openings in the links for receiving the eccentric shaft 39 being elon-. gated slightly, for-purposes to be hereinafter described.

The front ends. of the shafts 38 and 39 are non-circular 40 in section and on these non-circular shanks are fitted socketed hubs 41, designed, to receive bearings in their sockets in order-that'thc shafts may be rotated through the medium of these hub wrenches. The rear end of shaft38 carries a take-up device, and the rear end of shaft 39 carries a power-compounding device. I will first describe the power device for moving the movable hcad inwardly.

The links 40 being mounted upon the shaft 38 in the 'fixod head, may, in the rotation of the shaft 39 oscillate to accommodate the throw of the eccentric shaft 39' which bears at the outer end of the slot when power is being applied to the shaft. Referring to Figs. 3, 4, 5 and 13, it will be seen that the rear end of shaft 39 is non-circular in section, and on the shank thus provided 55. are two companion ratchet wheels 42, the peripheries of these ratchet wheels being formed with semi'circular recesses 43. I 44 indicates a fulcrum block pivoted at 45 to the base casting, and which is recessed to receive the hub of one of the wheels 42. A lever 46 is pivoted 60, upon this fulcrum block and this lever carries two weighted dogs 47, which are pivoted on each side thereof near its fulcrum point, each dog carrying lateral projections 48 designed to engage the semi-circular mcesscs in the peripheries of the ratchet wheels 42. A

63' stop 49 is also pivoted to the lever 46 to cooperate with lever in certain operations of the machine. The lever 46 is preferably provided with a socket in its outer end, see Fig, 2, in which mounted a removable exten- ,sion 50. Y

. Referring now to where the heads are shown should the dogs be in the position shown in Fig. 13. This motion imparted to shaft 39 is in the direction of the arrow shown in Figs. 1 and 2.

I will now describe-the operation-of my improved machine.

The bridge plate 15 with the proper curvature to its upper face is inserted in position and the wedgekeys of proper width are also placed in position. The wheel is now introduced between the wedge keys and the wedges 17 are employed if necessary. The next operation is to throw down the lovers 24 to initially setthe wedge'kcys against the tire. I The movable head during all of these operations is away from the fixed head, the shafts 38 and 39 being in the positions shown in Figs. 8 and20. A felly clamp is now arranged in position to hold the wheel down in its seat and this ielly clamp consists of a bracket 51 extending up from the rear face of the frame plate, said bracket carrying a cross piece 52 which is pivoted to its up pe'r end, see Fig. 3. This cross piece has a screwshaft53f mounted therein, said screw having a head by means of which it'may be turned, the lower end of said screw, swiveling in a clamping head 54, see Fig. 12, which is designed to contact with the felly of the wheel. 55 indicates a standard pivoted to the front face of the base framing and whose upper end is bifurcated. The lcvcr 56 is mounted in the bifurcated end of thisstandard, the hub of which lever is in the form of an eccentric so that after the folly clamp 54 has been adjusted manually against the folly of the wheel, the lever 56 may be raised and finally clamp the swivcled head 54 against the felly. The .wheel is now secured in position and the next operation is to finally set the gripping keys which is accomplished preferably by inserting a bar 57, see dotted lines Fig. 1; in the hub wrench of shaft 38 which hub is now rotated to the right or in the direction of the arrow shown in Fig. forcing the gripping keys firnilyinto the tire'an'd drawing the movable head toward the fixed head until the parts assume. substantially the positionshown in Fig. 21. During all of this time the shaft 39 has remained idle and after thc tirc has been gripped and the resistance becomes too great for the lever 57 to be longer effective, the lever 50 is operated so as to rotate the shaft 39 in the direction of the arrow shown in Fig. 20. A'succcssion of movements imparted to the lever 50 will result in the weighted (logs driving the companion ratchet wheels with considcmblc power so that the movable head is forced toward the iixcd head the weighted dogs to hold them on the upper side of thc separated, ,it will be obvious that half of a revolution instead of onthe lifting stroke which would result when the shaft 39 has made one-half of a revolution to substantially the position shown in Fig. 22.

It will be obvious from the position shown in Fig. 20 to the position shown inFig. 21, that some means must be provided for locking the shaft 38 against backward rotation, otherwise the rotation of shaft 39 will be ineffective. This means consists in a take-up key whose construction is best shown in Figs. 2, 4, 5 and 11. This take-up key, indicated at 58, is in the form of a wedge operating between a fixed abutment in the form of a guide-way 59 on the rear-link 40, and a fiat-faced weighted collar 60 loosely mounted on the rear end of shaft-38, a washer 61 being provided for holding the weighted collar 60 in position.

62 indicates the weight or pendant which is employed for the purpose 'of presenting the flat face of collar 60 at all times towards the abutment 59. 1

and when Br s as is rotated to drawthemovable head towards it, as forinstance, in finally setting the gripping keys, the parts being in the positionshown in Fig. 21

- after this operation, th abiltment 59 will be moved outwardly on awayfrom the fiat-iaced collar 60. The take-up wedge will'autematically fall,(by gravity) into the widened space and when the limit of motion, im parted by the handle 57 is reached, it follows that the shaft 38 will be locked in its new position or in the position shown in Figs. 21 and 22. To insure the take up wedge being home, it may be struck a blow-by a hammer, as will be readily understood;

After.the parts have reached the ppsition shown in Fig. 21 power is applied to the shaft 39 either through the hubwrench 41 if a light tire is to be set or through the compound leverage arrangement through-the me dium of the handle 50. In any event,'the half revo.

lution imparted to shaft 39 will result in moving the head 3 towards :the stationary head until the throw 0 the eccentric shaft 39-is exhausted. j

Means are provided for taking up lost motion and avoiding the return ofthe movable head to its former position after the eccentric shaft 39 has exhausted its throw, otherwise the spring 14 would tend to loosen: the. grip of the gripping keys. This means consists of the lever 57 which is left in the socket wrench on the end of-shsi'a: 38 so as to provide an over-balancing weight which. becomes effective to rotate -t he shaft38 the instant that the shaft 39 has exhausted its throw-and starts to return on the second half of its revolution.

-Weig ht 57 drops gradually and rotates the shaft 38 in the direc tion 0f the arrow causing the linksto move toward the left to retain the ground gained by the previous inward movement of head 3. Not only are =the links forced outwardly by the droppingof lever 57,

the links bearing on shaft 39 in the meanwhile, but the take-up wedge automatically drops, due to the widening of the space between the flat face of thecollar and the abutment 69, so that when the. shaft 39 isin the position shown in Fig. 23 in readiness to have'the power again applied thereto to force the head 3 inwardly, the shaft 38 has moved to the position shown in said Fig. 23

and the take-up wedge now locks shaft 38 in its new position to prevent backward rotationthereof as before described. The next operation of the. shaft 39 from the position shown in Fig. 23 to the position shown in Fig. 24 will cause the head 3 to move inwardly, as before described, until the eccentric shaft 39 has exhausted its throw when the operation of taking up motion during the time that the shaft 39 is onthe second half or return portion "of its revolution isrepeated as before by the lever 57 dropping until the shaft 38 is in the position shown in Fig. 25 and the take-up wedge is home. The final operation of rotating the shaft 39 is now repeated untilthe shaft has exhausted its throw, as shown in Fig. 25. Itwill be seen from the above that the head 3 has moved from its outermost position to itsinnermost position and if we assume that the parts marked X and X represent points of a tire, that said points will have been moved from their separated position to a position of coincidence. Of course, this does not actually happenin upsetting tires but diagrammatically, we have illustrated the tire ashaving been cut, the'contiguous ends being .drawn together.

If the bearings for'the links on shaft 38 are one-half inch off center, the eccentric-shaft thus having a one inch throw, and if the bearings for the links on shaft 39 are three-sixteenths of an inch'off center so that the eccentric shaft 39 has three-eighths of an inch throw, it follows that the distance traveled by the movable head starting from a position where the throws ol the eccentric shafts are" in opposition and the heads are most widely separated will be equal to the total of the throws of both shafts or one and three-eighths ofv an inch. This distance may be divided as followsi After a wheel has been placed in position andthe levers 24 depressed, the operation of lever 57, in finally fixing the gripping keys and initially setting the tire (if it is light enough to be set by the application of manual power applied through this medium),will consume onchalf'of an inch movement; The first half revolution of shaft 39 will move the head 3 three-eighths of an inch closer to the fixed head, making a total movement of the head when the parts are in the position shown in Fig. 22, of seven-eighths of an inch. .The next movement of the head starts when the parts are in the position shown in Fig. 23 and the next half revolution of the shaft 39 will move the head 3-another three-eighths of an inch closer to the fixed head or to the position shown in Fig. 24, making in all, a movement of one and oneeighth inches. The next movement is effected after the shaft 38 has been placed in the position shown in Fig. 25 and the shaft 39 again rotated but in this instance the full stroke of the eccentric on shaft 39 is not imparted to the links because of the insufficient throw of the eccentrics on shaft 38, consequently :there is only one quarter of an inch movement imparted to the head 3 on the final operation of shaft 39 which makes a total of one and threeeighths inches movement imparted to the head 3 from its outermost to its innermost position.

To release the-wheel after the tire has been setgthe levers 24 are first thrown up to deprive the gripping keys of the tension of springs 25, and thelever 57 moved -in the opposite direction to reversely-rotate the outwardly to release the gripping keys. The handle 56 is now depressed to release the ielly clamp which maybe thrown back and the Wheel taken out of the device. The spring 14 assists the head 3 in its out-- ward movement.

In setting heavy tires, there is never sufficient amount of pressure yielded by spring 14 torelease the gripping keys and thus the elongations in the links .prevent the opening of the machine'on the last half turn of the eccentric in the movable draw head should the lever 57 be left, out of its-socket. The elongations in the links allow the operator to up-set the tire andsuccessfully operate the machine without placing the le-' ver 57 in the eccentric hub 41 until after he has turned the eccentric in the movable draw head one revolution.- Spring 14 takes up all lost motion and is very essential .to the successful operation of the machine, since if there were no means for taking up lost motion the ma: chine would be partly ineffective to the extent that the lost motion would have to be taken up by the large eccentric, as the movable draw head would slide 130-" ward the stationary head of its own weight until the eccentric came in contact with the inner walls of the elongated slots' in the links to arrest'its inward movement.

This application is a continuation of'an application, so far as the principal features are concerned, filed by me on or about June 14, 1902, Serial No. 111,658.
